  43 The input can also be a JAR file produced by \f[CB]pack200\f[R] with an
  44 effort of \f[CB]0\f[R], in which case the contents of the input file are
  45 copied to the output JAR file with the \f[CB]pack200\f[R] marker.

  53 .SH DESCRIPTION
  54 .PP
  55 The \f[CB]unpack200\f[R] command is a native implementation that
  56 transforms a packed file produced by the \f[CB]pack200\f[R] into a JAR
  57 file for web deployment.
  58 An example of typical usage follows.
  59 In the following example, the \f[CB]myarchive.jar\f[R] file is produced
  60 from \f[CB]myarchive.pack.gz\f[R] with the default \f[CB]unpack200\f[R]
  61 command settings.

  67 .TP
  68 .B \f[CB]\-H\f[R]\f[I]value\f[R] or \f[CB]\-\-deflate\-hint=\f[R]\f[I]value\f[R]
  69 Sets the deflation to be \f[CB]true\f[R], \f[CB]false\f[R], or \f[CB]keep\f[R]
  70 on all entries within a JAR file.
  71 The default mode is \f[CB]keep\f[R].
  72 If the value is \f[CB]true\f[R] or \f[CB]false\f[R], then the
  73 \f[CB]\-\-deflate=hint\f[R] option overrides the default behavior and sets
  74 the deflation mode on all entries within the output JAR file.
